Furnaces usually last longer than air conditioning units. The average lifespan for air conditioning units is 15 to 20 years, while furnaces generally last 15 to 30 years. However, if your furnace is more than 15 years old and you need an AC replacement, it makes more practical—and financial—sense to replace your air conditioner and furnace at the same time.
M&M, your trusted AC technician, explains why below:
How an Aging Furnace Can Affect Your New Air Conditioner’s Energy Efficiency
New AC units feature fresh technology that can lower your cooling costs. It’s estimated that you can reduce your cooling costs by 20 to 40 percent by installing a new, more efficient AC unit. However, any energy savings you get from installing a new air conditioner can be negated by an aging furnace, which shares the same blower motor fan with your air conditioner.
What to Look for in a New AC Unit and Furnace
- High Seasonal Energy Efficiency Rating (SEER) and Annual Fuel Utilization Efficiency (AFUE) ratings – The SEER rating (which ranges from 13 to 21+) and the AFUE (which is a percentage from 80% to 100%) indicate the efficiency of AC units and furnaces respectively. The higher the SEER and AFUE rating, the more efficient the AC and furnace unit.
- ENERGY STAR® Certification – An ENERGY STAR certification is proof an AC unit or furnace has met the Environmental Protection Agency’s performance standards.
